Documentation
An Endpoint
type that holds the path
and the method
.
Gets used as the key in the API
hashmap. Modify defEndpoint
or any Endpoint
value you want using the path
and method
lenses to tweak.
>>>
defEndpoint
"GET" /
>>>
defEndpoint & path <>~ ["foo"]
"GET" /foo
>>>
defEndpoint & path <>~ ["foo"] & method .~ HTTP.methodPost
"POST" /foo

.

A type to represent extra notes that may be attached to an Action
.
This is intended to be used when writing your own HasDocs instances to add extra sections to your endpoint's documentation.
DocNote | |
|
newtype ExtraInfo api Source #
Type of extra information that a user may wish to "union" with their documentation.
These are intended to be built using extraInfo. Multiple ExtraInfo may be combined with the monoid instance.
data DocOptions Source #
Documentation options.
DocOptions | |
|
Instances
Show DocOptions Source # | |
Defined in Servant.Docs.Internal showsPrec :: Int -> DocOptions -> ShowS # show :: DocOptions -> String # showList :: [DocOptions] -> ShowS # |
defaultDocOptions :: DocOptions Source #
Default documentation options.
Type of GET (or other Method
) parameter:
- Normal corresponds to
QueryParam
, i.e your usual GET parameter - List corresponds to
QueryParams
, i.e GET parameters with multiple values - Flag corresponds to
QueryFlag
, i.e a value-less GET parameter
A type to represent an HTTP response. Has an Int
status, a list of
possible MediaType
s, and a list of example ByteString
response bodies.
Tweak defResponse
using the respStatus
, respTypes
and respBody
lenses if you want.
If you want to respond with a non-empty response body, you'll most likely
want to write a ToSample
instance for the type that'll be represented
as encoded data in the response.
Can be tweaked with four lenses.
>>>
defResponse
Response {_respStatus = 200, _respTypes = [], _respBody = [], _respHeaders = []}
>>>
defResponse & respStatus .~ 204 & respBody .~ [("If everything goes well", "application/json", "{ \"status\": \"ok\" }")]
Response {_respStatus = 204, _respTypes = [], _respBody = [("If everything goes well",application/json,"{ \"status\": \"ok\" }")], _respHeaders = []}
Response | |
|
combineResponse :: Response -> Response -> Response Source #
Combine two Responses, we can't make a monoid because merging Status breaks the laws.
As such, we invent a non-commutative, left associative operation
combineResponse
to mush two together taking the status from the very left.
defResponse :: Response Source #
Default response: status code 200, no response body.
Can be tweaked with four lenses.
>>>
defResponse
Response {_respStatus = 200, _respTypes = [], _respBody = [], _respHeaders = []}
>>>
defResponse & respStatus .~ 204
Response {_respStatus = 204, _respTypes = [], _respBody = [], _respHeaders = []}
A datatype that represents everything that can happen at an endpoint, with its lenses:
- List of captures (
captures
) - List of GET (or other
Method
) parameters (params
) - What the request body should look like, if any is requested (
rqbody
) - What the response should be if everything goes well (
response
)
You can tweak an Action
(like the default defAction
) with these lenses
to transform an action and add some information to it.
Action | |
|
combineAction :: Action -> Action -> Action Source #
Combine two Actions, we can't make a monoid as merging Response breaks the laws.
As such, we invent a non-commutative, left associative operation
combineAction
to mush two together taking the response from the very left.
Default Action
. Has no captures
, no query params
, expects
no request body (rqbody
) and the typical response is defResponse
.
Tweakable with lenses.
>>>
defAction
Action {_authInfo = [], _captures = [], _headers = [], _params = [], _fragment = Nothing, _notes = [], _mxParams = [], _rqtypes = [], _rqbody = [], _response = Response {_respStatus = 200, _respTypes = [], _respBody = [], _respHeaders = []}}

docs :: HasDocs api => Proxy api -> API Source #
Generate the docs for a given API that implements HasDocs
. This is the
default way to create documentation.
docs == docsWithOptions defaultDocOptions
docsWithOptions :: HasDocs api => Proxy api -> DocOptions -> API Source #
Generate the docs for a given API that implements HasDocs
.
extraInfo :: (IsIn endpoint api, HasLink endpoint, HasDocs endpoint) => Proxy endpoint -> Action -> ExtraInfo api Source #
Create an ExtraInfo
that is guaranteed to be within the given API layout.
The safety here is to ensure that you only add custom documentation to an endpoint that actually exists within your API.
extra :: ExtraInfo TestApi extra = extraInfo (Proxy :: Proxy ("greet" :> Capture "greetid" Text :> Delete)) $ defAction & headers <>~ [("X-Num-Unicorns", 1)] & notes <>~ [ DocNote "Title" ["This is some text"] , DocNote "Second section" ["And some more"] ]
docsWith :: HasDocs api => DocOptions -> [DocIntro] -> ExtraInfo api -> Proxy api -> API Source #
Generate documentation given some extra introductions (in the form of
DocInfo
) and some extra endpoint documentation (in the form of
ExtraInfo
.
The extra introductions will be prepended to the top of the documentation, before the specific endpoint documentation. The extra endpoint documentation will be "unioned" with the automatically generated endpoint documentation.
You are expected to build up the ExtraInfo with the Monoid instance and
extraInfo
.
If you only want to add an introduction, use docsWithIntros
.
docsWithIntros :: HasDocs api => [DocIntro] -> Proxy api -> API Source #
Generate the docs for a given API that implements HasDocs
with any
number of introduction(s)
class HasDocs api where Source #
The class that abstracts away the impact of API combinators on documentation generation.
Instances
class ToSample a where Source #
The class that lets us display a sample input or output in the supported content-types when generating documentation for endpoints that either:
- expect a request body, or
- return a non empty response body
Example of an instance:
{-# LANGUAGE DeriveGeneric #-} {-# LANGUAGE OverloadedStrings #-} import Data.Aeson import Data.Text import GHC.Generics data Greet = Greet { _msg :: Text } deriving (Generic, Show) instance FromJSON Greet instance ToJSON Greet instance ToSample Greet where toSamples _ = singleSample g where g = Greet "Hello, haskeller!"
You can also instantiate this class using toSamples
instead of
toSample
: it lets you specify different responses along with
some context (as ErrorMessage
) that explains when you're supposed to
get the corresponding response.
Nothing
Instances
toSample :: forall a. ToSample a => Proxy a -> Maybe a Source #
Sample input or output (if there is at least one).
singleSample :: a -> [(Text, a)] Source #
Single sample without description.
defaultSamples :: forall a. (Generic a, GToSample (Rep a)) => Proxy a -> [(Text, a)] Source #
Default sample Generic-based inputs/outputs.
class GToSample t where Source #

Note: we use combinators from Universe.Data.Helpers for more productive sample generation.

The class that helps us automatically get documentation for URL captures.
Example of an instance:
instance ToCapture (Capture "name" Text) where toCapture _ = DocCapture "name" "name of the person to greet"

class ToAuthInfo a where Source #
The class that helps us get documentation for authenticated endpoints
toAuthInfo :: Proxy a -> DocAuthentication Source #
class ToFragment t where Source #

Example of an instance:
instance ToFragment (Fragment a) where toFragment _ = DocFragment "fragment" "fragment description"
toFragment :: Proxy t -> DocFragment Source #

Generate documentation in Markdown format for
the given API
.
This is equivalent to
.markdownWith
defRenderingOptions
markdownWith :: RenderingOptions -> API -> String Source #
Generate documentation in Markdown format for
the given API
using the specified options.
These options allow you to customise aspects such as:
- Choose how many content-types for each request body example are
shown with
requestExamples
. - Choose how many content-types for each response body example
are shown with
responseExamples
.
For example, to only show the first content-type of each example:
markdownWith (defRenderingOptions
&requestExamples
.~
FirstContentType
&responseExamples
.~
FirstContentType
) myAPI
